To all whom it may comm: 7

Be it known that I, Cmnnns H. Areas, a citizen of the United States, residing at Salem in the county of Salem and State of New ersey, have invented certaln new and useful Improvements in Can-F lling Machines, of which the following IS a speclfication.

The object of my invention is to prov de simple and efiicient mechanism for pressing fruits, or other substances, into the cans whereby the cans will be completely filled without crushing the fruit, and the invention consists in the parts and combination 5 and arrangement of parts hereinafter describedand claimed.

In the drawings I Figure 1 is a front elevation of a filling machine constructed in accordance with my an invention,

Figure 2 is a rear elevation of the same, Figure 3 is a top plan view'of Figure 1, the hopper being removed to more clearly illustrate certain parts of my invention,

Figure 4 is a section taken on the line 4-4 of Figure 1, certain parts of the machine being omitted for clearness of illustration,

Figure 5 is a section taken on the line 55 of Figure 1,

Figure 6 is a section taken on the hue 6-6 of Figure 1, certain of the parts bein omitted for clearness of illustration,

'%igure 7 is a section taken on the line 7-7 of Figure 6, and

Figure 8 is a sectional developed new of the machine shown in Figure 1 illustratlng the cycle of operation in a step by step movement.

In the drawings, 10 indicates the frame of the machine, 11 the driving shaft, 12 a bevel gear on the driving shaft meshing with a bevel gear 13 fixed to an upri ht shaft 14, 15 a gear fixed to the uprig t shaft and meshing with a gear 16 fixed to and adapted to actuate an upright shaft 17 which car-- ries a bevel gear 18 meshing with a bevel gear 19 adapted to actuate a worm shaft 20 which feeds the empty cans 21 to the machine. The ar 15 also meshes with a gear 22 rotatably' mounted on the frame and carr ing a delivering disk 23 24 represents a disk mounted upon the frame and u on which the empty cans are deposited as t ey come from the can feeding mechanism. Immediately above disk 24 there is a canositioning wheel 2 the. is ke ed to and rotates with shaft 14, 27 represents the funnels through which the materials are fed from the measuringv receptacles to the cans. These funnels are connected by a central o0 hub 28 keyed to shaft 14 but capable of vertical movement thereon. The funnels have cylindrical throats, adapted to receive plungers, and depart from the usual funnel shape in having a part of their periphery vertical while the other part 29 inclines inwardly from the throat in such manner that by rotation of the hub, the inclined parts will be successively brought under the dischar e opening 32 through which the ma-' teria s are fed through the bed plate 310i the turret 30. 33 represents the measuring wheel, 34 the measuring receptacles and35 the hopper. The central hub 28 of the funnels is provided with a collar 36 which is embraced by U-shaiped lu s 38 carried by a split nut 37 on a threade part 14 of shaft 14. By turning the nut upwardly or downwardly the position of the funnels may be vertically adjusted to enable them to function with different sizes of cans. A. plun er 39 arranged to reciprocate vertically, is provided for each funnel 27. Each plunger has an upwardly extending arm 40 secured to a plate or bar-41 extending downwardly 1 outsi' e the funnel and carrying at its lower end a roller 42 adapted to travel one. camtrack 43. The low point of the cam-track is indicated at new the high point at 45 as shown in Figure 8. in order that the cam -track may be adjustedvertically it ,is' hinged to the frame at 46 and supported at its opposite side by a bolt 47 taking loosely through a lug 48 extending from the cam track, a nut 49 being provided to support 9:, the lug.

In operation rotation of the central hub 28 of the funnels moves the rollers on the camtrack and they are carried alternately to the high and low points of the track thereby reciprocating the 'plun ers in the funnels.

By constructing the nnels with the .inclined surface and so positioning them that the tomatoes or other fruit to be canned will fall uponthe incline and slide to the turret 1 before the plunger engages with them crushing is avoided and the fruit is pressed into the cans by the positive action of the plungers induced by the rollers upon the camtrack.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence ll do not limit myself to the precise construction set forth, but

. consider that l am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what ll claim as new and desire to secure by Letters Patent is 1. In a can filling machine, a bed plate having a discharge opening; a measuring wheel rotatable upon the bed plate; a shaft adapted to rotate the measuring wheel; a hub mounted on the shaft and carrying a series of tunnels, each funnel having an inclined inner face, a vertical outer face and a vertically walled throat, and plungers arranged to reciprocate upon'the vertical walls of the tunnels and to take into the throats.

2. In can fillingmachine, a bed'plate having a discharge opening; a measuring wheel rotatable upon the bed plate; a shaft adapt ed to rotate the measuring wheel; a hub mounted on the shaft and carrying a series of integral tunnels, each funnel having an inclined inner face, a vertical outer face and a vertically walled throat, and plungers arranged to reciprocate upon the vertical walls of the funnels and to take into the throats.

3. In a can filling machine, a bed plate having a discharge opening; a measuring wheel rotatable uporfthe bed plate; ashaft adapted to rotate the measuring wheel; a hub splined to the shaft and carrying a series of funnels, each tunnel having an inclined inner face, a vertical outer face and a menace vertically walled throat; plungers arranged to reciprocate upon the vertical walls of the tunnels, and means for adusting the position of the hub 0n the shaft,

4. In a can filling machine, a bed plate having a discharge opening; a measuring wheel rotatable upon the bed plate; a shaft adapted to rotate the measuring wheel; a hub splined to the shaft and carrying a series of funnels, each funnel having an-inclined inner face, a vertical outer face and a vertically walled throat; plungers arranged to reciprocate upon the vertical walls of the funnels; means for vertically adjusting the position of the plungers, and means for adjusting the position of the hub on the shaft.

5. In a can filling. machine, a bed plate having a discharge opening; a measuring wheel rotatable upon the bed plate; a shaft adapted to rotate the measuring wheel; a hub mounted on the shaft and carrying a series of funnels, each funnel having an inclined inner face, a vertical outer face and a vertically walled throat; a cam track; a

plunger for each funnel, each plunger having an upwardly extending arm secured to a plate extending downwardly outside the funnel; rollers carried by the plates adapted to travel on the cam plate and reciprocate the plungers, and means for vertically adjusting the cam track.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES H; AYARS.
